Tilion Raises $500,000 — Startup Funding India, October 2026

Startup funding in India is going to ever-younger, deeply technical teams: AI startup Tilion has raised $500,000 (about ₹4.8 crore) from Y Combinator, joining its Fall 2026 batch, ET Edge Insights reported on October 15, 2026.

The startup is led by 22-year-old Arman Luthra, who went to school in Jammu and now heads the company as CEO alongside three friends he met in college: Md Shahrier Islam Arham (CTO), Kazi Fardinul Hoque and Abdul Basit Tonmoy. The venture began in a college dormitory.

Browser infrastructure for AI agents

Tilion builds AI browser infrastructure: for an AI assistant to book travel, retrieve documents or complete online forms, it must navigate websites and finish the job — a slow browser wastes time and a blocked browser stops the task entirely. Its browser engine, Fortress, has reached 100,000 installations, and more than 170 companies now use Tilion's technology. The team cites public evidence for its engineering: Tilion ranks first on ComputeSDK's Browser Lifecycle benchmark and BrowserArena's latency leader-board. Among the competitors ranked below it in those tests is Browserbase, which announced a $40 million funding round in 2025 at a $300 million valuation.

A founder worth watching

Luthra's range runs well beyond code: his political cartoons were published in an Irish political-science textbook, and at 19 he launched Scribia, an AI study app that hit 5,000 installations in its first two weeks. He later worked on education-policy research at the American Enterprise Institute. YC's backing gives the four founders a global stage — the accelerator's alumni include Airbnb, Stripe and India's Meesho.
